PATTERN-TRANSFER MACHINE.

I Specification of Letters Patent.

Patented July 4, 1922.

Application filed July 19, 1919. Serial No. 312,089.

T 0 all whom it may concern: Be it known that I,;PA'UL YOHNS, a citizen of Germany, and a resident of'the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Pattern-Transfer Machine, of which the following is a full, clear, and exact description.

This invention relates to a pattern-transfer machine, and aims to provide a machine of this nature by means of which patterns, such as embroidery patterns, may be trans ferred from a master pattern to those patterns used by needle workers, in a more efiicient and economical manner.

It is well known in connection with embroidery patterns which are placed face down upon cloth and a hot iron, or other suitable instrument, run over the back of the same, which results inthe transfer of the imprint upon the face of the cloth, that the greatest reason for the-expense in con-' nection with them is the method of using expensive copper cylinders on the surface of which the design is engraved by hand and from which the so engraved design is printed on to the paper in the ordinary rotary way.

In view of the above, I have constructed a machine which does not use an engraved copper cylinder to print upon the paper, but

instead a master pattern made out of tracing linen, or even a fiber sheet, is utilized, through which the design to be printed is perforated with a perforating machine of well-known construction.

Another object of the invention is, as briefly brought out, the provision of a machine by means of which it will be possible to turn out transfer patterns at a much faster rate of speed, in that it has heretofore I been impossible to commercially make transfer patterns from a sheet of tracing linen character of certain structure which will permit the thickness of the dotted lines to be varied at will.

. Reference is had to the attached three sheets of drawings which illustrate one practhrough my device illustrating a tension roll employed in connection therewith.

Fig. 6 discloses an enlarged exaggerated construction of the master'pattern.

In all of these views, like reference numerals designate similar parts and the reference numeral 1 indicates a casing, which may-be provided with inlet and outlet slots 2 and 3.

Any suitable source of power (not shown) may be employed, which serves to impart motion to driving belts or other suitable power-transmission structure, 'as indicated by the reference numerals 4 and 5. A belt 5 passes over a pulley 6 which is keyed to a shaft passing through the interior of the casing 1 and upon which is mounted a drum 7. Adjacent both ends of the shaft there is mounted upon the same. a gear wheel 8 which meshes with gears 9, in turn meshing with gears 10, which serve to impart to the drum 12, by means of engagement with the gear 11, rotational movem'entaccurately synchronized with respect to the drum 7. I

A further drum 13 is mounted upon a shaft adjacent the opposite end of the casing from that in which the drums 7 and 12 are situated, and intermediate the drums 12 and 13 there is positioned a trough 1 1 which is mounted upon slideways 15 and provided with a handle 16 by means of which it will be possible to withdraw such trough from within the casing 1. Rotat-ably mounted within the trough 14 is a further drum 17 which is mounted upon a shaft 18 projecting throu h the side walls of the casing and provided with a pulley 19 over which passes the belt 4 for a purpose hereinaftermore fully specified.

A tension roll 20 is positioned directly below the trough 14 either inside or outside of the casing 1. A master pattern 20 is now "clamped together by means of a holdiliig 1 passed around the drums 13 and 12, as well as around the roll 20,.and has its ends firmlyi pasting device, such as illustrated in g 1 which device includes a pair. of pivoted clamping plates '21which may be moved by means 0 I operated by means of ascrew 24. It will be understood that one of the free ends of the master pattern is placed below one of the plates 21 and the set screw 22 operated so as to hold this end in applied position. The pattern is then threaded through the various parts and around the drum 12 and'roll 20, and its opposite end passed around the drum 13 and brought underneath the'second clamping plate 21, which is in turn operated by means of the set screw 22 to retain it in applied position. In the usual manner, the ends of the pattern are coated with .paste and placed under the bar 23, which is then projected by means of the screw 24 and brought to bear tightly against the joint constructed between the two ends of the pattern,

' so that the same may be tightin ever particular. Subsequent to the pattern rying and forming a tight joint, the clamping plates 21 are released'so that a free movement of the pattern may be effected.

It will be appreciated that the pattern will stretch, particularly under the varying temperatures to which it will be subjected, and in view of this I have provided the side walls of the casing 1 with guide slots 25 in which are slidably mounted JOIIIIlalS 26 housing the ends of a shaft upon which a r011 27 is mounted. A cord-and-weight attachment 28 acts.

upon the slidable journal 26 so as to tend to move the same upwardly ,and, consequently, retain the proper amount of tension upon the pattern 20. The tension, which is not provided for by the roll 27, is produced by means of the tension roll 20 which is mounted upon a shaft 29 which has its ends journaled within openings provided in the ends of screw-threaded rods 30. Any suitable arrangement for projecting and retracting the set screws 22 and a slidable bar 23 menses quential projection or retraction of the rods 30 carrying the tension roll 20 around which the pattern 20' I passes. A roll 35 extends across the casing and to one side of the drum 17. An endless piece of felt, or other suitable material, 36 passes around the roll 35 "and the drum 7 andbears' with its outer face against the outer face of the pattern 20, asclearl shown in Fig. 1.

For a purpose hereina ter more fully specified, certain parts of the device, such as the drums 13, 17 and 12 and the interiorof the trough, are heated. This heating may be accomplished by any suitable arrangement, but for the sake of convenience Iv have illustrated an ordinary steam-heating arrange ment by means of which steam may be introduced into the heating system by a pipe 37,

from which it flows through any suitable uni0n.38 to the axle 39, which is provided with apertures 40 which serve to distribute the heating .fluid to the interior of the drum 13. To prevent condensation by permitting a slight circulation through'the drum, I have provided at the opposite end of the axle 39 a small petcock 41' which may be slightly bent topermit the escape of a small amount of fluid. The axle 18 of the drum 17 is simi-' larly apertured, as indicated by the reference numeral 42, as is also the axle 43 of the drum 12, all of these axles being connected with a suitable source of heat so as tov Warm the drums which they mount. Reference being had to Figs. 1' and 2, it will be noted that a 'pipe 44 passes around the base of the trough 14 so that the contents of such trough will be heated through'engagement with the hot sides. of such pipe.

A y suitable mixture 45, such as wax and ink, is placed Within the trough 14 and is retained in a fluid state by means of the heat- 1 ing system aforedescribed. The drum 17 is driven by the belt 4,-and dipping below the surface of the mixture 45 causes a certain amount of such mixture to impinge upon the upper face of the drum, which is preferably constructed of material such as steel. Upon reaching a certainpoint in the circumference of the drum 17, the fluid mixture is removed from the outer surface ofsaid drum by means of a scraper blade 46 which terminates at a point adjacent the front face of the roll 35 and, consequently,

pattern 26. A regulating blade 47 is mounted directly above the blade 46 and has its outermost edge terminating in a plane approximatelylparallel to the olfter ed e of' the blade 46, so that the thickness 0 the fluid passing outwardly over the blade 46 .may be varied at the point of contact with .the pattern 20. A second scraper blade 48 is plvotally mounted, as indicated at 49, to

the side walls of the trough 14 and is normally swung upwardly into engagement with the inner face of the pattern 20 bymeaiis of a rope and associated weight 50, so that the surplus mixture which has been applied to the inner face of the pattern 20 by means of the blade 46 and plate 47 may be removed and guided again into the trough 14 where, due to the heat, it will quickly become fluid again.

It will readily be appreciated that the plate 47 and particularl the blade 46, must becapa 'le of any num er of adjustments. For this reason, referrin more particularly to the plate 47, I ave swingingly mounted thesame between a pair of Sue pending arms 51 extending from the side walls of the casing 1. The adjustment of the arms 51 is secured by means of a pair of set screws 52 bearingagainst a suitable abutment 53 associated with one of the arms 51. It will be seen that this method of mounting the plate 47 permits such plate to be swung through an arc the center of which is .at a point corresponding to the Q point of pivoting of the arms.51 and the side walls of the casing 1. A second adj ustment is provided by means of mounting the plate 47 pivotally to the lower ends of the.

arms 51, as aforestated.

The blade 46 is pivotally mounted upon a bar 54, the ends of which are secured to the outer ends of a movable bar 55 which is slotted, as indicated by the reference numeral 56, at a portion approximately intermediate its two extremities, so that by virtue of a headed pin 57 it will be possiblefor the bar 55 to be rotated around its slotted portion 56 and also to be moved longitudinally with respect to the pin 57. A pair of rollers 58 and 59 extend transversely through the trough 14. Secured to the outer end of the roller 59 is a forked rod 60 engaging a pin 61 secured to a rod 62,

the lower end of which is screw-threaded and projects through a pivotally-mounted set nut 63. Secured to the outer end of the roller 58 is a rod 64 to which is pivotally secured, approximately intermediate its extremities, the inner end of a screw-threaded rod 65 projecting through a pivotallymounted set nut 66. A link 67 extends, as

clearly shown in Fig. 3, between the upper end of the rods 64 and 55.

Paper 68, upon which the attern is to be transferred,'enters through t e slot 2 in the casing 1 aTd passes over a rigid bar 69 and subsequently a bar 70 slidably'mounted in slots 71 formed in the side walls of the casing,.which latter bar serves the purpose of smoothing and applyingtension to the paper 68; Subsequently the paper passes around the roller 72 which is adjustably mounted,

in the casing 1, which roller serves to also regulate the tension upon the strip of felt, or other material, passing around the roll 35 and drum 7.

Referring now more particularly to Fig.

6, it will be seen that the master pattern 20, if made of paper, includes a number of perforations which, upon the outer sur-- face of the pattern, present upwardly and outwardly extending side walls, as indicated by the reference numeral 69. If made of linen, as indicated by the second view of Fig. 6, it will be seen that the master pattern .includes perforations the sides of which extend upwardly and inwardly, as indicated by'the reference. numeral 70.

In operation, assuming that the master roll 20 has been properly placed around the drums 12 and Bend the tension roll 20, .as-

well as passin around the rolls 27 and 35, and that the p ate 47 and blades 46 and 48 have been properly positioned, it will be seen that the paper 68 may be passed over the bar 69, under the bar 70, around the roll v 72, and follow the course of travel of the felt strip passing around drum 7 and roll 35 by virtue of the roll 72; The proper tension will have been imparted to the master pat-,

tern 20, and the speeding of the feltstrip and pattern will have been absolutely synchronized by means of the system of gearing evolved by myself. The ink 45 being in a fluid state, and the drum 17 being revolved by means of a pulley 19, the ink will follow the outer surface of the drum around and pass outwardly around the. upper surface of the blade 46, its. flow bein properlyregulated by means of the p ate 47; and so against the inner face of the pattern 20' and through the perforations in the same on to the outer face of the paper 68, which is at the point of contact with the pattern and ink provided with a soft bed by means of the felt strip. The surplus ink is now scraped from the inner face of the pattern 20' by means of the blade,48, which also serves to force the residue of the ink within the perforations in the pattern, through and on to the paper 68. Subsequently, the pat tern, passing over the hot drums 12 and 13, will cause any ink secreted within the perforations of the'pattern to be removed therefrom due to the fact that it-reduces such ink to a fluid state and causes it to drop out of the pattern.

This operation may be repeated indefinitely, and it is to be readily appreciated that the machine may be run at any speed withln reason, and it will produce as perfect a reproduction at a fast speed as at a slow means of'my tern, costing merely a fraction of the expense involved in connection with the construction of the usual copper cylinder, and which master pattern may be used an in definite number of times. Further, it will be noted that by virtue of the uni ue construction of the perforations, as disc osed in Fig. 6, and the soft bed presented to the out- "wardly projecting side walls of the perforal tions upon the outer face of themaster pattern, the ink will pass through such perand consequently the master pattern in a heated condition, whereby printing fluid upon lodging in the perforations is heated and caused to flow.

A pattern transfer machine comprising a perforated master pattern, rolls supporting-the same, means to maintain the rolls and consequently the master pattern in a heated 'condition, whereby printing fluid upon lodging in the perforations is heated and caused to flow, and means' to pass the .printing fluid upwardly through the perforated pattern into, contact with the material to'be printedupon.
